parts, all as hereinafter more lfully described,`

claimed and killustrated in the accompanying drawing, wherein:

Fig. 1 is aside elevationY of a gear embodying. the present. inventionillustrating the same' as the driving gear of an egg beater; and

Fig. 2 is an edge elevation thereof. s

While the present gear and its hub eral application and use, it isdesigned particularly for use as the driving gear of an egg beaterwherein the gear is mounted between the sides of the beater frame andacts to space the sides of the frame.

Heretofore, it has been customary in order to mount the driving gearbetween the sides of the frame of an egg be-ater to provide a hubconsisting of one or more individual pieces secured to the gear at itscenter and projecting outwardly from the body of the gear to bearagainst the inner surfaces of the egg beater frame. This typeconstruction preventsI any lateral play or displacement on the part ofthe gear and at the same time spaces and braces the sides of the eggbeater frame. The gears of the prior art including hubs made up of anumber of separate parts has been diflicult and expensive to constructand assemble.

The present gear is designed to -accomplish the purposes of the priorart gear and at the same time have all of its elements of the hubthereof formed integrally with the body of the gear, thereby reducingthe number of parts as well as the steps of construction and assembly.

Reference being had more particularly to the drawing, I0 designates theframe of an egg beater provided with a handle Il. The sides I2 of theframe I0 are spaced one from the other and rest parallel and at theirlower ends are provided with mountings or bearings I3 in which thebeaters I4 are mounted for rotation. Adjoining the lower ends of thesides I2 of the frame I0 and secured to the beaters I4 are gears f5 bywhich the beaters I4 are driven and rotated. A driving gear I6 ismounted between the sides I2 of the frame lll and meshes with the gearsI5 whereby the rotation of the driving is of gent gear I6causesthe'rotation ofthe gears I5 and lconsequently the beaters I4. p

- In order to create a hub at the center of the gear I6 in such-form asto prevent any lateral play or displacement of the gear I6 and to ll thespace between the sides I2 yof the frame, the bodyy of the` gear II.V ateach side of the center thereofis cutl to create a tongue I1, the innerend of whichisA integral with the body of the gear at a point adjoiningthe center thereof. The formation of these tongues I1 from thebody ofthegear I6 creates a pair of diametrically disposed openings I8 in the bodyof the gear resting along a diameter lof the gear and extending from thecenter of the gear.y toward the periphery thereof. -These tongues I 'Iare bent laterally to rest atA right angles to the body of the gear i6and extend outwardly topointsad-l joining the inner surfaces of thesides IZ of the frame I0. Here each tongue I1 is again bent at rightangles to create a bearing member I9 parallel to the gear I6 andextending across the line of the center of said gear to terminateapproximately in the plane of the right angularly bent portion of theopposed tongue I'I. The body of the gear I6 vat its center and thebearing members I9 of the tongues I'I which cross the line of the centerof the gear I6 are each provided with a rectangular aligned opening 20for the reception of the driving shaft 2|.

The driving shaft 2I is rectangular in cross section and passes throughcircular openings in the sides I2 of the frame I0 and is received in andpasses through the rectangular openings 2B in the gear I6 and bearingmembers I9 so that the shaft 2l is free to rotate in the sides I2 of theframe I0 and is rigidly and fixedly connected or keyed to the gear I6and to the bearing member I9 whereby the rotation of the shaftZI rotatesthe gear I6. At one end the shaft 2l is provided with a crank or handle22 adjoining the outer face of one of the sides I2 of the frame I0,while the opposite end of the shaft 2i is headed up, as at 23, againstthe outer face of the opposite side I2 of the frame II).

It is to be observed that as each of the bearing members I9 of the hubabove described operates against the inner face of one of the sides ofthe frame I0, the gear I6 is held against lateral displacement upon theshaft 2l or between the sides I2 of the frame I and the latter arereinforced and maintained in their spaced positions.

It is also to be noted that the gear I6 is provided with an integralhub, the construction and formation of which is relatively inexpensiverequiring no assembling whatever.

What is claimed is:

1. The combination with a gear, of a tongue formed and spaced from saidgear, said tongue having a shaft receiving opening therein.

2. 'I'he combination with a gear having an aperture in the centerthereof, of a tongue formed from the body of the gear'at one side ofsaid aperture and bent to occupy a position at right angles to the bodyof the gear, the end of said tongue being lateral to cross the line ofthe center of the gear.

3. The combination With a gear having an aperture in the center thereof,of a tongue formed from the body of the gear at one side of saidaperture and bent to occupy a position at right angles to the body ofthe gear, the end of said tongue being laterally bent to cross thelineof the center of the gear and having an opening therein in alignmentwith the opening in the center of the gear. y

4. The combination with a gear having aY central aperture therein, atongue formed from the body of the gear on each side lof the aperture,said tongues being positioned. at right angles to the body of the gearupon opposite sides thereof and having their ends bent laterallyto crossthe line of the center aperture of the gear.

5. The combination with a gear having a central aperture therein, atongue formed'from the body of the gear on each sideof said aperture,said tongues being positioned at 'right angles to the body of the gearupon opposite'sides thereof and having their ends bent laterally tocross the line of the center opening of the gear, said tongues havingopenings in the laterally bent part in alignment with the centeraperture of the gear.

6. 'Ihe combination with a disc, of dametrcally disposed tongues fonnedfrom the body of the said disc and bent to occupy positions at angles tothe disc and having shaft receiving openings adjoining theirextremities. 5

'7. 'Ihe combination with a disc, of diametrically disposed tonguesformed from the body of the said disc and bent to occupy positions atright angles to the disc, the ends of said tongues being bent laterallyto the bodies thereof to cross the l0 pivotal line of the disc.

' 8. 'Ihe combination with a. disc, of diametrically disposed tonguesformed from the body of the said disc and bent to occupy positions atright angles to the disc, the ends of said tongues being 15 bentlaterally to the bodies thereof to cross the pivotal line of the disc,said disc and tongues being provided with aligned apertures.

9. A gear comprising a disc having an opening therein, and a tongueformed and spaced from 20 said disc and provided with an opening alignedwith the disc opening.

10. A gear comprising a disc having an opening therein, and tonguesformed and spaced from said disc and upon opposite sides thereof, said25. tongues having openings aligned with the disc opening.

11. IThe combination with a disc, of tongues spaced from said disc, saiddisc and tongues having shaft openings aligned transversely of the 30disc and tongues.

l2. The combination with a disc, of tongues integral with said disc andparallel thereto, said disc and tongues having shaft openings alignedtransversely of the disc and tongues. 35-
